You can use simply intent.putExtra instead of worrying about which variant like put_____Extra to use.

When extracting the value, you can use intent.extras to get the Bundle and then you can use get() on the Bundle and cast to the appropriate type. This is easier than trying to figure out which intent.get____Extra function to use to extract it, since you will have to cast it anyway.

The below code works whether your data class is Serializeable or Parcelable. You don't need to use arrays, because ArrayLists themselves are Serializeable, but you do need to convert from MutableList to ArrayList.

When in doubt, JLS will help:

If two methods of a class (whether both declared in the same class, or both inherited by a class, or one declared and one inherited) have the same name but signatures that are not override-equivalent, then the method name is said to be overloaded.

So it's not "changing the parameters", it is about not override-equivalent. To find out what that is, you go to another chapter, that says:

Two method signatures m1 and m2 are override-equivalent iff either m1 is a subsignature of m2 or m2 is a subsignature of m1.

And the same chapter explains what subsignature is:

The signature of a method m1 is a subsignature of the signature of a method m2 if either:

• m2 has the same signature as m1, or

• the signature of m1 is the same as the erasure (§4.6) of the signature of m2.

How you interpret your above methods is an exercise left to you.

The best I have so far is { person: message.person, tag: 1 }.

Is there shorthand initializer syntax to achieve this?

No, this is still they way to go.

hoping that a property name would magically be inferred from person

You should separate creating your menu from your content. Please review the following example. I decoupled your menu, component, and event logic into meaningful phases.

Express regular request handlers are expected to have no more than 3 arguments as you can verify here.

And looking up Function.length:

length is a property of a function object, and indicates how many arguments the function expects, i.e. the number of formal parameters. This number excludes the rest parameter and only includes parameters before the first one with a default value.

It becomes clear why the second function works and the first one doesn't:

Instead of this:

You can apply a function to the column that will make the item_id "uniform", then can drop_duplicates()

Those are stray bytes like *, %, etc. prefixed with some of the lines.

The stray bytes appear to be a custom stream multiplexing protocol, allowing STDOUT and STDERR to be sent down the same connection.

Using stdcopy.StdCopy() interprets these custom headers and those stray characters are avoided by removing the protocol header for each piece of data.

This seems like a bug introduced by a bug fix in this ticket. The result was wrong for outer joins. Hence the need to add a Project node (packing of the struct) before the Join node.

However, we end up with this kind of query plan:
